Dear LOR user,

Thank you for being a big part of this community. To better support the initiatives around open educational resources in the state of Michigan, all resources on the Michigan Virtual Learning Object Repository (LOR) are being moved to #GoOpen Michigan on September 30th, 2018. During the transition, our LOR will be moved to an archived state, not allowing new user registration or new content to be added. An email with more details was sent to registered users of the LOR in September. To make use of the great resources on the platform, we encourage you to create an account and add your own new resources to the #GoOpen Michigan platform.

Diameter and Circumference Lab


In this lab activity, students are asked to:
- Collect data on the diameter and circumference of several round objects
- Graph this data to explore the relationship between diameter and circumference
- Analyze the graph to determine a numerical value of Pi

In my class, this is the first lab of the semester and is intended to introduce students to the type of data collection, graphing, and analysis that will be expected of them throughout the term. I have also created a teacher video, which walks through this lab so that students know exactly how it should be completed. (
